WebTropisms are responses by an organisms in a particular direction as a result of an external stimulus.Plants show phototropism (growth responses to sunlight) and geotropism (growth responses to the force of gravity).These tropisms are a result of growth factors which accumulate in different parts of the plant. Phototropism is a directional response to … WebTropisms require auxins. The hormone that changes the direction of the growth of the plant is an auxin. They do this by elongating plant cells through increasing and decreasing cell division, based on where they are active. Auxins are made in the tips of the roots and stems and move through the plant via diffusion.
